Totally lost.

Post by Grayhound6 » Tue Feb 07, 2017 9:18 pm

I have been reading for some time now about all sorts of radio "info" and for the most part comprehend it well enough for a conversation. From how am waves differ from fm, to QRP and SSB. Where my head starts to spin is at the terms 2 meter, 10 meter, decimeter, and 70cm. I get that those are another term for their corresponding frequency range, but have no clue why. Also if someone could direct me to almost a linear illustration representative of the frequencies in order that would be amazing.

2 meter, 10 meter, and 70cm and similar are references to the wave length of the frequency ranges.
The wave length would be from the top of one sine wave crest to the top of the next of the frequency range.
Any RF energy is a sine wave and actually a form of AC RF energy.

You might want to take a look here for a colored chart that shows the different ham bands and frequencies they use.

Here is another ham radio frequency chart that is a little different in the presentation.
